P1 DB25 port
 P2 solder pads for 50 positions
RN1-3 Resistor Networks

No oscillator, clock might be generated by Chips P82C612...
J1 outline hints at a previous configuration of a right angle socket with retentive catches.
P1 has the solder pads for 50 positions, while P1 is a DB25. Maybe there was a different external port?
